Comment # 14 on bug 1165946 from Franck Bui

Then it's a duplicate of bsc#1137373.

Can you please report your case back to upstream:
https://github.com/systemd/systemd/issues/12953 ?

It might help making upstream considering this issue as important.

Meanwhile, if you don't have any btrfs file systems on your setup, you can keep
btrfsmaintance package uninstalled. I don't know the reason why this package is
always installed...

Also I opened bsc#1165780 in order to improve btrfsmaintance which should
mitigate the issue you're facing.
